Can you me with this, ?

write an equation for each sentence.

the sum of 4x and -3 is 8

an athlete trains for 115 min each day for as many days as possible. write an equation that relates to the number of days (d) that the athlete spends training when the athlete trains for 690min.

4x + (-3) = 8
(Hopefully)

As for the second one, I ASSUMED it would be this but I'm kinda busy and my ADHD brain just needed a break from what I was doing so just equate it for me, will you? And tell me if I was right or wrong because I have NO IDEA what I'm doing.

Let the number of days he trains for be x
So, 115x = 690

The correct answer is b because when you convert it to a decimal you get 3.166667. you will have to round this answer. since it has a seven at the end, the 6 will not have a line over it because it does not go on forever. you round the six to a seven because the next number is larger than five.
